To all whom it may concern: by screws 12, to the frame 13 or some other Be it knownthat I, JOHN A. HULIT, a suitable part of the recording device, citizen o the United States, residing at Chiequipped with a -bedor table 14 carrying cago, in the county of Cook and State of the record sheet or strip of paper or the Illinois, have invented a certain new and like 16, propelled by suitable mechanism. 60

I mentioned screw, lock the arm 44 in posi Figure l is a front elevation of a record tion with the screw 48 in juxtaposition to ing telegraph machine embodying the printhe screw 40, or swing the arm 44 to the poriples of the invention, showing certain porsition shown in Fig. 3. The set screw 50 tion moved fo convenience of illustra it will be seen is screw threaded through the I 0 tion, this view corresponding to Figure 7 arm 44 in the ordinary manner. vVhen the v of said prior application. b v arms 38 and 44 are in normal position, that Fi ure 2 is an enlarged detail sectional is, when the screw point 48, Fig. 3, is swung iew of the lgunping device hi h CV81 t0 .ltS pOSltlOH behind the post fountain pen is secured to the rock shaft the point 48 directly above and opposite the 45 upon which is also mounted the armature p int 40, heynormally have between them l00 of the magnet, this view corresponding to and control the length of the stroke of the Figure 9 of said prior application. armature 52 of the magnet 28. But when Figur 3 i a ti l tion in Figure the arm 44 1s swung to the left as shown in 1 on line c 3-3, on a smaller scale,.being Fig. 8, the upper contact 48 is out of the j 50 similar to Figure 4 of said prior applica- Way of the armature, so that the armature tion, except that in this case, of course, the can be raised to a position asshown in Fig. other form of fountain pen is shown. 3. The armature 52 is rigidly secured by In the particular embodimentv of the in any suitable means to the shaft 104. The ti Shown in th drawing a. suitable rear end of the armature 52 is attached 5'5'base 10 is provided adapted to be'attached t One End f the spring 70, the other end. of which is attached to the shaft to any suitable support. Detachabl'y corn nected to the post 18 is provided the arm 100 and held in place by suitable set screw. 68. This arm 100 has an upturned end 109. serving as a bearing for the one end of the shaft 10 the other end of which shaft is suitably pivoted in the post 18. At the outer end of the shaft 102 is a rectangu lar enlargement or block 106 held in place by apin 108, the outer end 108 of which serves the purpose of a positioning pin for the flat metallic clip 110 which is held. in position by the set screw 112. This screw passes throughv a suitable opening in the clip 110. The outer end of the clip is curved to embr re and securely hold the fountain pen no. The point 118 is adapted to bear upon the tape 16. The positioning pin 108 and the holes in the clip as well as the hole for the set screw 112 are accurately made and positioned so that by removing the screw no the pen 11.6 and. the clip 110 may be lifted as a unit from enlargement with thei controlling device and yet restore quickly and accurately to its own original position of adjustment, in which position the pen can function in the way that it should in con-- nection with the tape 16. It will be understood that the armature 52 is detachably and adj ustably secured to the shaft 104i by a set screw Set. It will be understood that spring '70 serves to hold. the armature 52 in its normal raised position against the contact point 18, and when the contact is removed out of the way it operates to rotate the shaft 10f, thereby raising the armature 52 to the position shown in Fig. 3, and likewise the pen 110 to the correspondingly raised. position from which position the pen and clip may be conveniently removed. without any danger of marking up or interfering with the tape 16.

From the foregoing it will be seen that the marking device (which is the fountain pen 11(3) and the armature 52 (the latter being composed of an arm which is adjustable on the rock shaft 104 and which supports the armature proper 152 directly above the magnet spools it being understood that the entire magnet comprises two of these spools arranged side by side) oscillate in. unison about a horizontal axis common thereto, the armature arm 52 and the foiiintain pen 11G workin up and down in parallel vertical planes which are spaced apart a distance for convenience of operation of the machine as a whole. The magnet pulls the armature down, against the adjustable screw 10, and when the magnet is de-enern'ized, the spring pulls the armature arm 52 upward against the screw 18, and this is the normal position of the armature, so that the fountain pen is normally raised a distance above the surface of the tape. With this arrangement. and by the provision of the screw 8 1: by which the armature is secured to the shaft 105i (without this screw the armature is loose on the shaft) inc armiu ture marking; device are relatively adjustable about the said axis, so that by looseninp; the screw 8i, while the armature is held in engagement with the screw dB, the point of the pen or marl zing device may be raised and lowered to obtain the desired adjusnnent, and by then. tightening the screw er the pen or marking device wll be held. in its adjusted position relatively to the an. ature. it will be 'lcrstood, of course, that this adjustment is obtained by rocking or OSClllut 1;); the shaft 10% in the arm of the armature, so that the armature is in one sense relatively adjusted on the shaft, while loose thereon and then secured thereto by the tightening; of said screw. Thus the upturned end portion 102 of the bracket 101 forms one bearing for the rock shaft, while the upper end of the post 18 forms the other bearing for said rock shaft, and it will be seen that the bearing- 102 disposed between the armature and the fountain pen or marking}; device, whereby the latter is disposed in. an overhanging position and in a position in which it can be easily adjusted or taken out and replaced. The fountain pen of course. is susceptible of endwise adjustment in the spring clip or holder 110, as the latter holds the barrel of the pen by frictional grip or pressin'e thereon, so that this ar'ijustment is possible if necessary or desirable. With this arrangem nt, therefore, the horizontal axis which con'nnon to the pen and armature is disposed l1 etween the upper and lower ends of the pen or marking device, so that the pen or marking device is easily tilted or vibrated or operated in the desired manner. it is not necessary for the pull of the magnet to raise the entire weight of the pen, nor is it necessary for the spring" 70 to raise the entire weight of the pen or marking device, as the weight of the latter is very well balanced at opposite sides of said axis of oscillation or tilting movement. Thus, the upper end of the fountain pen assists the spring 1 0 in raising the pen point from the tape, which would not be the case if the weight of the fountain pen or mariting; device was disposed entirely at one side of the axis of movement, and in such case the spring would be under the necessity of lifting the entire weight of the mar-kiln; device. ..his tends to make the ii'istrument more satisfactory, in some ways. of course, inasmuch as the work of the magnet and the sprin are reduced to the requirement of merely tilting); or oscillating a rock shaft about the axis of which the marking device is fairly well. balanced, so that the weight of the marking device does not interfere llO p in position.

with the rapid and accurate operation of the machine by the electrical impulses transmitted through the coils of the magnet.
